Description

[0001] APPARATUS FOR MEASURING IMPLANT MOBILITY [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an implant dynamicity measuring apparatus, and more particularly, to an implant dynamicity measuring apparatus capable of measuring the degree of vibration of an implanted implant without affecting the fixation force of the implant.

Implant aneurysm is a device for measuring whether implanted implants are properly placed with desired fixation.

At present, the implant dynamometer is widely used to measure implant dynamics by using the repulsive force and repulsion rate information of the implants after striking the dental implants.

When the upper part of the implant is exposed, the device is fixed to the object to be tested by fastening an exposed upper cuff or a solid abutment, or when the upper part of the implant is not exposed, Healing abutment or solid abutment is fastened to the object to be scored.

In this device, the values of the repulsive force and the repulsion rate obtained each time the object is touched 16 times for the measurement of the shaking motion are calculated, and the average of these values is displayed as the final shake. For this measurement, when the contact tip provided at the front of the apparatus is placed at a distance of about 0.6 mm to 2.0 mm and the operation button provided on the apparatus is operated, the contact tip is automatically touched 16 times.

This device has a high possibility of affecting the fixation force of the implant during 16 strokes even if the impact force is weak because it directly touches the implant with a distance. Especially, in case of an implant which does not have sufficient fixation force, The possibility was high.

In addition, for tacking, the user must position the device such that a distance of about 0.6 mm to 2.0 mm is provided between the contact tip and the object to be tacked. It is difficult for the user to determine this exact position in the field, It was difficult to obtain a reliable fluctuation value.

The tapered rod 130 is for tapping an implant, which is an object to be touched. The tapered rod 130 has a contact tip 131 at the front and a strike portion 132 at the end. In addition, the tilting rod 130 is formed with a long installation groove 133 in the front side thereof. An elastic spring 134 is fitted to the striking part 132 and the elastic spring 134 is restricted in movement by a spring stop block 135 provided so as to be linearly movable through the striking part 132.

The position sensor permanent magnet 140 is provided to fix the tapered rod 130 on the tapered rod 130 by means of the mounting body 141 to inform the positional change of the tapered rod 130.

The position sensor 150 senses a change of the position of the position sensor permanent magnet 140 and senses the movement of the beating rod 130. The position sensor 150 is fixedly positioned above the beating rod 130. [ The tapered rod 130 is inserted through the through hole 152 formed in the tapered rod 15 and the tapered rod 15 is fixed to the main body 110 by bolts or other fastening means.
